Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . anical transmission with an interposed clutchsimilar in principle ff) the ordinary antomolrile firive. and the other a rigid connection between engine and wheelsby means of gears, or rods, or both. Gear-Clutch Transmission Gear-clutch transmissions have been in use for a longtime in small industrial locomotives and rail cars, mostlyin France and in Germany for powers ranging from 30to 200 hp. They represent a combination oi clutches, ofa set of gears of the sliding type, of universal joints, andbevel gears. Sometimes chains, jackshafts, and rods arealso used. The well-known Renault rail cars and theDeutz and Schneider industrial locomotives employ trans-missions of this kind. In this country the McKeen carwas at one time very much in vogue. The Baldwin100-hp. gasoline locomotive, of which several hundredwere built during the World ^^■ar. was provided witli agear-clutch transmission. In 1923 the Swiss Locomotive Works in Winterthurbuilt a 0-4-0 switching locomotive with four pairs of. Fig. 2—Meyer Type Hydraulically Operated Friction Clutch gears always in mesh and four hydraulically operatedfriction clutches of the Rieyer type (Fig. 2). One gearwheel of each pair is made of two parts which arescrewed together and can rotate on the hubs of twoinside disks which form the clutch. The disks and wheelshave concentric tapered grooves and are pressed againstthe wheels by hydraulic pressure, which thus engagesand disengages the clutches. The disks can slide on thekeys by which they are set on the hollow shaft. Xor-mally the disks are kept disengaged by oil which fills thelower passage of the shaft at a constant pressure: whennecessary, they are engaged by admitting oil into theupper passage at a pressure in excess of that in thelower passage. The four speeds are: 5, 9><, 15 and Bevel gears are used for reversing. The locomotive weighs tons and is dr
